  • 摘要: 研究了粉末活性炭、硅藻土和膨润土等3种常用吸附剂对三氯乙醛（CH）的去除作用，并以南方某水源原水为研究对象，分析3种吸附剂对于CH前体物（CH1d和CHFP）的去除效果。结果表明，膨润土和粉末活性炭适用于对CH的去除，最大去除率分别为95.93%和86.86%。225 mg·L-1投加量条件下，前15 min膨润土和粉末活性炭对CH吸附效果最快，2种吸附剂对CH去除率分别为63.36%和51.84%；反应2 h后，对CH的吸附已达到饱和，此时膨润土和粉末活性炭对CH去除率分别为89.36%和61.75%。粉末活性炭和硅藻土适用于对CH前体物的去除，最适投加量均为30 mg·L-1，此时对CH1d和CHFP的去除率分别为57.49%和75.21%、28.27%和50.19%。可根据CH的风险程度高低选择硅藻土或粉末活性炭对CH前体物予以去除。
    Abstract: The removal of chloral hydrate (CH) and its precursors by powdered activated carbon (PAC), diatomite, and bentonite from a drinking water source in southern China was monitored. The daily CH yield (CH1d) and the CH formation potential (CHFP) indicated that bentonite and PAC were suitable for the removal of CH, with maximum removal rates of 95.93% and 86.86%, respectively. After the first 15 min, maximum adsorption rates of CH on bentonite and PAC were achieved at a dosage of 225 mg·L-1, with corresponding removal rates of 63.36% and 51.84%, respectively. Furthermore, the CH adsorption was saturated after 2 h, with corresponding removal rates of 89.36% and 61.75%, respectively. In addition, PAC and diatomite were suitable for the removal of CH precursors, both having optimal doses of 30 mg·L-1. PAC and diatomite exhibited removal rates of 57.49% and 75.21% for the CH1d, respectively, and 28.27% and 50.19% for the CHFP, respectively. The employment of PAC or diatomite to remove CH precursors depends on the level of risk associated with CH.
